Abstract

La présente invention concerne des mousses de polyuréthane souples constituées par la réaction d'un quasi-prépolymère hydrophile, d'eau et d'un polymère polyol en présence d'un tensioactif de silicone et d'un copolymère séquencé d'oxyde d'éthylène/d'oxyde d'alcylène supérieur. Les mousses font preuve de densités et de rémanences à la compression de préférence faibles, et présentent de bonnes propriétés thermiques et de capillarité. Les mousses sont utiles dans les applications de literie et d'autres applications de confort dans lesquelles elles sont exposées à la chaleur du corps et portent au moins une partie du poids de l'utilisateur. Les propriétés thermiques et de capillarité contribuent au confort perçu pour l'utilisateur.
